The practical value of an electric kettle mainly lies in its fast heating speed. Generally, it only takes 5-8 minutes to boil a kettle of water. An electric kettle can be said to be an energy-saving and energy-saving fast heating device. Furthermore, it is convenient to use, with automatic power off when water is turned on, ensuring safety during use. It is recommended that households choose all stainless steel fast electric kettles to avoid safety issues when using plastic kettles.

After about 5 minutes of connecting the electric kettle to the power supply, the steam causes the bimetallic plate of the steam temperature sensing element to deform, and the top opening switch contacts disconnect the power supply. If the steam switch fails, the water in the pot will continue to boil until it is dried, causing a sharp increase in the temperature of the heating element. There are two bimetallic plates located at the bottom of the heating plate, which will rapidly increase in temperature due to thermal conduction, expand and deform, and disconnect the power supply. Therefore, the safety protection device for electric kettles is designed very scientifically and reliably.
